AI Technical Summary
Technical Problem
In traditional slide rail devices, the ball bearings are prone to detaching from the sliding frame, resulting in uneven movement, increased wear, vibration, and noise, and lacking an effective buffering mechanism.
Method used
The L-shaped sliding groove, consisting of an upper slide, a lower slide, and a side slide, along with pulleys in the pulley groove, combined with buffer mechanisms on both sides of the side slide, including buffer cylinders or buffer springs, forms a stable sliding connection and absorbs impact energy.
Benefits of technology
It achieves stable and smooth sliding, reduces wear and vibration noise, extends the service life of the slide rail device, and improves the user experience.

Abstract
The utility model belongs to the technical field of slide rail device, concretely relates to a pulley guide structure and slide rail device. The pulley guide structure of the utility model realizes stable sliding connection by L type sliding groove which is formed by upper slide, lower slide and side slide and pulley which is arranged in pulley groove, effectively prevents pulley dislocation, and ensures sliding smoothness, simultaneously sets up inverted U type buffer storage abutting member with buffer mechanism on both sides of side slide, and buffer mechanism is realized double absorption impact energy by buffer accommodation cavity which is formed by fixed part and elastic arm, and the utility model discloses significantly reduce the collision vibration when the inner bottom rail is retracted and avoid the vibration and noise caused by rigid collision. The structure has the functions of anti-dislocation and buffering, solves the problem of easy falling of traditional ball bearings, reduces impact damage through buffering design, thereby realizes high stability, low wear and impact resistance in compact space, and the width limit design of buffer accommodation cavity ensures that the buffer mechanism is always in pre-compression state, providing continuous buffering force.
